Windows Hello is Microsoft’s answer to the problem of passwords. These days almost all smartphones allow you to unlock your device with face id or a fingerprint. All premium priced iphones have come with this for a couple of years. However going passwordless is not so common on a PC.
Some business PCs have supported logging in with a smartcard or fingerprint reader. However, security was originally quite alien to PCs. The first computers didn’t even need passwords. To get onto one the administrator had to know you and setup your account. Then as more people got access it became necessary to secure systems with passwords. PCs were not originally connected to networks and they went through a similar security transformation. A transformation accelerated by the internet.
Your user account name (username) is often public information. An email address is common. Your password is something you keep secret. These are your personal credentials. Unfortunately, people don’t easily create complex passwords that can’t be cracked. They will make it easy for themselves or use the same password on multiple systems.
To make accounts more secure there is multi-factor authentication. This is an additional step on top of a password. This can be a physical key that has to be plugged into a PC, an app on your phone or a text message with a code. All of these are being used.
Microsoft has developed Windows Hello that removes the need for a password. Windows Hello is a biometric identification process. A PC camera that meets the Windows Hello standard can be used or some other biometric element. One of the first devices to use Windows Hello was the Microsoft Lumia 950 smartphone. Most Microsoft Surface devices now support Windows Hello.
The cheapest way of getting your own PC to work with Windows Hello is with a USB fingerprint reader. This upgrade brings passwordless biometric id to your PC. As a driverless device you just plug it in and setup Windows Hello in settings. Once done you don’t have to type in a password.
I have been using this for a couple of days. It’s not revolutionary but it is convenient. For the price it’s a good PC upgrade.
